Oscillation criteria for second-order nonlinear differential equations with integrable coefficient
نویسندگان
چکیده
Oscillation criteria are given for the second order nonlinear equation y it) + a(î)/(y(0) ■ 0, where the coefficient a(i) is not assumed to be nonnegative for all large values of t. These results are concerned with the interesting recent ones of Wong's paper.
